8-8 DECK
The underside of the mower deck should be cleaned after
each use to prevent a buildup of grass clippings, leaves,
dirt or other matter. If this debris is allowed to accumulate,
it will invite rust and corrosion, and may prevent proper
mulching. The deck may be cleaned by tilting the mower
and scraping clean with a suitable tool (make certain the
spark plug wire is disconnected).
8-9 HEIGHT ADJUSTMENT
INSTRUCTIONS
CAUTION: Do not at any time make any
adjustment to lawn mower without first stopping the
engine and disconnecting the spark plug wire.
CAUTION: Before changing mowing height, stop
mower and disconnect spark plug cable.
Your mower is equipped with a central height adjustment
lever offering 5 height positions.
1. Stop mower and disconnect spark plug cable before
changing mower cutting height.
2. The central height adjustment lever offers you
5 different height positions.
3. To change the height of cut, squeeze adjuster lever
toward the wheel, moving up or down to selected
height. (Fig. 23) All wheels will be in the same height
of cut.

11-2 CUTTING BLADE
spark plug wire before working on the cutting blade to
prevent accidental engine starting. Protect hands by using
heavy gloves or a rag to grasp the cutting blades.
Tip mower as specified in separate engine manual.
Remove the hex bolt and washer which hold the blade
and blade adapter to the engine crankshaft. Remove the
blade and adapter from the crankshaft.
adapter for cracks, especially if you strike a foreign object.
Replace when necessary.
For best results your blade should be sharp. The blade
may be resharpened by removing it and either grinding or
filing the cutting edge keeping as close to the original
bevel as possible. It is extremely important that each
cutting edge receives an equal amount of grinding to
prevent an unbalanced blade. Improper blade balance will
result in excessive vibration causing eventual damage to
the engine and mower. Be sure to carefully balance blade
after sharpening. The blade can be tested for balance by
balancing it on a round shaft screwdriver. Remove metal
from the heavy side until it balances evenly. (Fig. 25)
Before reassembling the blade and the blade adapter to
the unit, lubricate the engine crankshaft and the inner
surface of the blade adapter with light oil. Install the blade
adapter on the crankshaft with the "star" away from the
engine. Refer to Fig. 25. Place the blade with the part
number facing away from the adapter. Align the washer
over the blade and insert the hex bolt. Tighten the hex bolt
to the torque listed below.
